The Spike's Tactical Gen II Billet Upper Receiver with Mil-Spec Barrel Nut provides functional upgrades that most other billet upper receivers don't offer. It's machined out of 7075-T6 billet aluminum, with the Gen II version offering more pockets to reduce the weight and a type III hardcoat anodized finish. M4 feed ramps are cut before the anodizing process to avoid reliability issues down the road. The side walls of the receiver are flared to eliminate accidental bolt release. The upper receiver has also been machined to accommodate the Magpul BAD lever or similar aftermarket bolt catch levers.

NOTE: This billet upper is not compatible with all aftermarket bolt catches.
